This describes how to upgrade Sync Box Firmware using the free dfu-programmer on linux. This only applies to the microprocessor; often it is also necessary to upgrade the CPLD.

The dfu-programmer software can be installed in Ubuntu like this: 

sudo apt-get install dfu-programmer

Make sure your version supports the sync box device (at89c5131): 

$ dfu-programmer --version
dfu-programmer 0.6.1
$ dfu-programmer --targets
targets:
   at89c51snd1c       at89c51snd2c       at89c5130          at89c5131
   at89c5132          at90usb1287        at90usb1286        at90usb1287-4k
   ...

Connect the sync box to the computer over USB. Don't do what the manual says: it's wrong! Instead to enable programming, do the following:

  1. Start with the sync box powered off and disconnected from USB
  2. Depress both the RESET switch and the PS_EN switch
  3. Power on the sync box
  4. Release the RESET switch
  5. Release the PS_EN switch
  6. Plug in the USB cable

When the device is properly detected it will show up in lsusb as something like: 

$ lsusb
Bus 002 Device 049: ID 03eb:2ffd Atmel Corp. at89c5130/c5131 DFU bootloader

To prove things are working, dump the contents of the device into a file: 

$ sudo dfu-programmer at89c5131:<USB_BUS>,<USB_DEVNUM> dump > part_dump.bin

where <USB_BUS> is the bus number from lsusb and <USB_DEVNUM> is the device number from lsusb. For the example lsusb output above, this would give us: 

$ sudo dfu-programmer at89c5131:2,49 dump > part_dump.bin

The contents of part_dump.bin can then be inspected with hexdump -C to confirm it's the sync box code and not some other nonsense.

Then to program the device the syntax is: 

act@wilson:~$ sudo dfu-programmer at89c5131:<USB_BUS>,<USB_DEVNUM> flash sync_box_v22_26sept2014.hex
